To connect the DTAM Plus terminal to an RS-485 device:
1. Make sure that the power to the DTAM Plus is off.
2. Use the proper cabling to connect the DTAM Plus communications port
to the port of the controller (PLC-5 channel 0 or SLC 5/03 or SLC 5/04
RS-232 port).
•
Use cable, Catalog No. 2707-NC4 for PLC-5 channel 0 RS-422
connection
•
Use cable, Catalog No. 2707-NC5 for PLC-5 channel 0 RS-232
connection. The 2707-NC5 cable converts the signals from the
RS-485 port to RS-232 levels.
•
Use cable, Catalog No. 1747-CP3 for SLC 5/03, 5/04, 5/05 port
connection
If you need to make your own cable, refer to the connection diagrams
in Appendix B. The maximum cable length is 200 feet (60.8 meters).
Important: The DH-485 network cable requires proper shielding,
grounding, and termination. Refer to Data Highway / Data Highway Plus
/ Data Highway-485 Cable Installation Manual (Pub. No. 1770-6.2.2).
3. The DH-485 connectors are not electrically isolated. If electrical isolation
is required, use Link Couplers (Catalog No. 1747-AIC) shown above.
!
ATTENTION: Electrical isolation using Link Couplers (Catalog
No. 1747-AIC) is required in applications where the distance
between the DTAM Plus terminal and the SLC is greater than 6.5
feet (2 meters).
4. Make sure that the communication parameters of the DTAM Plus terminal
match the host device.
5. Apply power and verify that communications are established.
